Abstract:
Intestinal failure-associated liver disease (IFALD) is a fatal complication of short bowel syndrome managed with parenteral nutrition. A clinical cohort study reported the usefulness of parenteral administration of fish-derived omega-3 fatty acids in improving IFALD; however, no biomarker has been developed as yet. The authors report the case of a preterm infant with IFALD complicated by extensive short bowel syndrome. Intravenous administration of omega-3 fatty acids were introduced using Omegaven®at the age of 4 mo for IFALD. The IFALD improved with an increase in Eicosapentaenoic acid (EPA)/ Arachidonic acid (AA) ratio (from 0.08 to 1.99) 7 d after the intravenous treatment. It is important to administer omega-3 fatty acids intravenously at an early stage for IFALD associated with extensive short bowel syndrome. A low EPA/AA ratio may be a serum marker of disease activity in IFALD.

DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...
